Battery box locking maintaining structure

Abstract

A battery box locking maintaining structure is used in battery assembling and disassembling of a power battery automatic quick replacing battery box system of a pure electro-mobile. The power battery automatic quick replacing battery box system of the pure electro-mobile comprises a battery outer box, a battery inner box, a battery assembling and disassembling mechanism and battery box locking maintaining mechanisms. The battery inner box is placed inside the battery outer box, two sides of the battery inner box are provided with locking holes matched with the battery outer box, and locking pin holes which are matched with the assembling and disassembling mechanism are formed in the bottom of the battery inner box. The battery outer box is of a framework structure. The battery box locking maintaining mechanisms are arranged on two side frames of the battery outer box and power is provided to the battery box locking maintaining mechanisms by a locking air cylinder.

Description

technical field [0001] The invention relates to a locking and holding structure, in particular to a battery box locking and holding structure of an automatic quick-change battery box system for a power battery of a pure electric vehicle. Background technique [0002] With the development of society, energy is increasingly scarce, environmental pollution is serious, and the potential impact of global climate change is huge. Electric vehicles with diversified power sources and zero emissions have become the development direction of future vehicles. In the past, the power energy of vehicles mainly came from petroleum products and various gases. However, with the decreasing of oil and gas resources and the increasingly serious problems of noise pollution, air pollution and global warming, it is necessary to develop and utilize environmentally friendly alternative energy sources, reduce CO2 Emissions have become the consensus of the people. In this context, electric energy, as a...

Problems solved by technology

However, there is a common problem in pure electric vehicles powered by rechargeable batteries. The charging time of ordinary vehicle batteries takes several hours, and they cannot quickly complete energy replenishment at gas stations like other oil and gas fuels, thus greatly limiting electric vehicles. the popularity of

[0003] In order to solve the above problems, the patent application No. 200810006771.6 proposes a method and device for quickly replacing large-scale battery packs. These methods generally use so-called high-voltage battery packs or full-voltage battery packs as replacement units to achieve rapid replacement of the entire battery pack. It is easy to install and unload, easy to maintain, expands the mileage, and is suitable for separate charging; but the invention does not realize automatic replacement, because most of the power batteries are lithium-ion polymer batteries, which have relatively high energy density and relatively large mass. Moreover, it belongs to the category of high-voltage electricity, and there is a certain danger in manual operation.

In addition, the existing quick-change system still needs a lot of manual inspection after the battery replacement is completed, and the reliability is not enough, so the battery replacement time is relatively long

[0004] In order to realize automatic replacement, the patent application No. 20111015101.9 discloses a quick battery replacement device for electric vehicles, which includes a track fixed on the ground and a frame slidingly connected with the track, a base is provided at the bottom of the frame, and a The pallet, the base and the pallet are provided with a lifting mechanism, and the battery positioning mechanism is also provided on the electric vehicle battery quick replacement device, including a correction arm and a pressure rod. This invention provides a compact, accurate positioning electric The quick and automatic battery replacement device for automobiles can save trouble and effort to complete the battery replacement work; however, the automatic replacement device is suitable for electric vehicles that load and unload batteries from the bottom of the vehicle, but not for electric vehicles that are loaded and unloaded from the side of the vehicle body, and the battery box is in the Passively accept replacement, the replacement efficiency is still low

[0005] In order to further improve the efficiency of replacing the battery box, the patent application number 20111009392.9 discloses a method for replacing the battery box and a battery replacement fixture, which uses the battery replacement fixture to carry the battery box, and the battery replacement fixture is installed on a movable quick-change system , the quick-change system completes the transfer of the battery box; the battery box is pulled out from the electric vehicle or charging rack through the rodless cylinder, and the battery box is pushed from the battery changing fixture into the electric vehicle or charging rack; the battery changing fixture Open or lock the battery box by unlocking the cylinder; complete the process of replacing the battery box; but the above-mentioned clamps directly act on the battery box during the battery box replacement process, because it is difficult to standardize the specifications and models of the battery objectively. Especially when clamping, it is easy to be unstable or unable to clamp, which cannot meet the needs of electric energy supplementary mechanisms similar to gas stations; and the battery box is passively accepted for replacement, and there is still a need for automatic replacement. with a certain gap
